(Cl. 21-4-27) This invention relates to an improved attachment for tank type vacuum cleaner s and has particular reference to such a device which will, by its use in conjunction with a vacuum cleaneigpurify the surrounding atmosphere and impart to the air a frag-rant and pleasing odor. 4

An object of this invention is to provide adevice of the character set forth which contemplates asplit', hollow spherical casing or housing through which a central open walled, tube engages and holds in posit-ions. cartridge compounded of crystal like and compacted mixture which will exude deodorizing and frag-rantly scented vapors when air is passed over the compacted mixture. H

Another object of this invention is the provision thereinof making the compacted mixture into solid cartridges which may be readily replaced when necessary.

A still further object of this invention resides in forming the cartridges in asemi-spherical shapeand so arranging same within the housingthat port-ions of same are exposed to the air passing therethrough; from the vacuumcleaner, which passing air willpick up the vapor fumes from the cartridges anddispell them into the surrounding atmosphere.

For further comprehension of the invention and of the objects and advantages thereof, reference will be hadto the following description and accompanying drawings, and to the appended claims in which the various novel features of the inventionare more particularly set torth.

Referring. to the drawings in which like reference nu merals refer to like parts, designates, generally, a tank-type vacuum cleaner and isan annular attachment nipple having receiving slot formations 13 adapted to receive an annular slotted connecting means 14. The nipple 12 of Fig. 6 has a reduced shank for use with a vacuum cleaner having a smaller discharge orifice. The said slotted connecting means 14 is formed upon one section 15 of a holder in the form of a hollow spherical casing or housing. A second section 16 of the hollow spherical housing is joined to the first mentioned section 15 by means of bayonet fastening means 17 and is formed with an outlet opening 18 Brackets 19, in cross-wire arrangement are secured to thesemi-spherical section 16 and extend to the outlet opening 18 (Figs. 2 and- 3)-. Similar brackets 20 are formed upon the slotted connecting means 14 and extend to an inlet opening 21 which is formed upon the semi-spherical section 15. The said brackets 19 and 20 function as spacers or separators Between the semi-spherical sections 16 and 15 respec tively and flanged thimhles 22 and 23 respectively. The said flanged thimbles 22 and 23 engage within the open ends of a tube 24 having openings 25 along the wall of same andhold the tube in alignment with the outlet opening 18 and inlet opening 21.

Scented material in the form of semi-spherical cartridges 2'6 and 27 having acentral opening are adapted to engage over the tube 24. The said cartridges 2'6 and 2'7 comprise a compacted porous substance which is moulded to semi-spherical form and scented to exude vapors which expand into chambers 28 and 29 and into the tube 2 4 where they are carried along with the air which enters at the opening 21 through the chambers and tube to the outlet 18 from whence the air is discharged into the surrounding. atmosphere. The cartridges are charged with a deodoriiing and perfuming substance and due to their form. are quickly-replaced with fresh cartridges when required. 7

The edges 30' and 31 of the central opening of the cartridges engage against lips 32 and 33 respectively, which are formed upon the thiriibles 23 and 22 respectively. The cartrid es 2'6 and 27, the tube 24 and the thiinbles 22 and 2 3 are held together by the semi-spherical housing sections 15 and 16 which are in turn held together By" means of bayonet locking members 34.

additional desddriz'iii-g ertaining unit 35 is attached to the vacuum cleaner or to the s'erii-i sphelieal' section 16, as shbwn in Fig. IA- and in detail in Figs. 8 through 10, the said unit 35 consists of scented material in the formof a disc 36 having a central beveled opening 37 and is provided with a holder in the form of a series of bent springlegs 38 which are adapted to be inserted at their free ends into the opening 18 in the semispher ical section 1 6, as shown in- Fig. 1A. A short distance from the disc 36 there is a ring 39 having a cen-* tral opening 40. The disc 36 and the ring 39 are made of per-en substance which is saturated with any suitable fragrant chemical and imparts an additional pleasant odor t0 the air as same is emitted from the device.

A dished or bowed out orificed disc 41 may be fixed the .tliiml t'rles removed from the ends of the central aibe and the cartridges slipped off of the tubes. manner the parts may be reassembled.

In the modified form shown in Figs. 11 and 12 the central tube 24 of the forms already described is replaced by a shorter tube 50 which widens at its inner end as at 51 and then flanges outwardly in the form of a circular plate 52 and abuts against an opposing similar plate formation 53 which is part of a tube 54. The tubes 50 and 54 are formed with openings or large orifices 55 and 56 and the plate 53 has formed upon it bosses or pins 57 which engage through orifices 58 in the plate '52. The cartridges are practically similar in formation as those of the form first mentioned. This form is desirable because the air flow through the central channel is arnplified by the expanded central section of the tube SO-54.

The modified form of the invention shown in Fig. 13 is characterized by the provision of a casing having reversible halves, 15' and 16, each having threaded screw holes 59 to secure a centrally disposed retainer band or strip 60. The casing halves are held together by the retainer band or strip 60, the strip encircling the casing at the juncture of the halves 1'5 and 16' and secured by screws 61 and '62 which fit into screw holes 59 in the casing halves. In this manner manufacturing costs are substantially reduced, the casing halves being interchangea'ble.

In the modified form of the invention shown in Fig. 14, the casing is made of two mating halves 63 and 64 each having annular slotted connected means 1-4 for attachment to the slotted formations 13 of nipples 12 and 12* (see Figs. 1-6). By this means, either end of the casing may be connected to the vacuum cleaner H.

The modified form of the invention illustrated in Fig. 15 is characterized by semi-spherical replaceable cakes or cartridges 65 and 66 each having a central opening adapted to engage over tube 24 and each comprised of scented, deodorant or germicidal or other material 67 enclosed in permeable, perforated or highly porous cake retentive paper 68. The paper covered cartridges 65 and 66 perm-it convenient handling of refills for the casing.

The modification illustrated in Fig. 16 is characterized by the provision of two opposed separating wedges 69 and 70 fitting in plug openings 71 and 72 provided in the casing half 78 thown and in the casing half not shown. Pressing the wedges '69 and 70 inwardly toward each other results in a prying action assisting greatly in the separation of the sections of the casing. The casing preferably is made as shown in Fig. 15 with press fitting halves and no bayonet locking lugs or members when the wedges are provided.

In any of the forms shown and described, the vacuum cleaner 11 may be used to vacuum clean unimpeded while the device is in operating position. Thus upon inserting the scenting attachment to the rear or exhaust end of the vacuum cleaner, air is constrained to pass around the scented material through the central tubes 24 or 54, as well as the circumferential passageways 28. Where member 35 is added, air passes through to carry off odors from the scented materials 36 and 39.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
